In our talk, we discuss technical aspects of measurement of Green's functions in the Hybridization-Expansion Continuous-Time Quantum Monte Carlo (CT-HYB) method. We introduce CT-HYB in general and explain the standard measurement procedure. We point out several weaknesses of the usual approach and propose an alternative measurement with improved estimators leading to a better statistics especially at low perturbation orders.
